What is the structure of a phospholipid?

Back

A phospholipid consists of a glycerol backbone, two fatty acid tails, and a phosphate group.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is active transport?

Back

Active transport is the movement of substances against their concentration gradient, requiring energy.

Front

What is the difference between diffusion and facilitated diffusion?

Back

Diffusion is the movement of molecules from high to low concentration, while facilitated diffusion uses transport proteins to help move molecules.
